The M13 coat is removed in the inner membrane of the bacterial cell, where it is sequestered during phage replication. It is subsequently used to package the newly replicated phage DNA to create progeny phage. Why would this make M13 less suitable than T2 for the Hershey and Chase experiment? Since both phage coat and phage DNA are injected into the bacterium and incorporated into progeny phage, it is impossible to determine which carries the genetic information. T2 worked because the phage coat could be shaken off and separated from the infected bacteria. 2. Draw the complementary strand for the following DNA sequence. I would have shown it as a double stranded molecule but I could not figure out how to rotate the figure! T
